Background
The vacuum consumable electrode arc furnace is a device widely used for smelting and forming metals at present, and is mainly used for smelting refined ingots of titanium and titanium alloy, zirconium and zirconium alloy, molybdenum and molybdenum alloy, niobium and niobium alloy, hafnium and special steel. With the development of equipment technology, the vacuum consumable electrode electric arc furnace can realize multi-aspect automatic control in the metal smelting process so as to ensure the product quality of cast ingots.
With the increase of the automation degree, the electrode rod and the dynamic sealing assembly of the vacuum consumable electrode arc furnace have more and more complicated structures, and the electrode rod and the auxiliary systems around the dynamic sealing assembly are more and more. For example, the top of an electrode rod of the existing vacuum consumable electric arc furnace is additionally provided with an X-Y adjusting function, a weighing function is added on the basis of the electrode rod and a dynamic sealing assembly thereof, a camera shooting function is added outside the electrode rod and the dynamic sealing assembly thereof, and even a smelting process, a resistance monitoring function and the like are added; therefore, the electrode rod and the dynamic sealing assembly thereof meet the insulation and sealing performance from single to be capable of meeting the requirements of micro-movement and weighing, are connected with the floating support, do not have interference relation with other mechanisms and the like. Therefore, the complexity of the electrode rod and the dynamic seal assembly thereof on the structure and the structure of the surrounding mechanism is obviously improved, and certain difficulty is caused in maintenance and overhaul of the dynamic seal assembly.
The commonly used maintenance and repair method of the dynamic seal assembly comprises the following steps: after the electrode rod and the dynamic seal assembly are integrally removed, the dynamic seal assembly and the electrode rod are decomposed to maintain and repair the dynamic seal assembly. This operation has the following drawbacks: firstly, requiring the hoisting height to be too high: because the electrode rods are generally arranged at the top of the equipment, and the length of the electrode rods is generally more than two meters, the requirement on the hoisting height is high; secondly, too many dragging mechanisms and complicated follow-up work: generally, the whole body is disassembled, at least a plurality of mechanisms such as an X-Y adjusting mechanism, a weighing mechanism, a camera shooting mechanism, a servo feeding transmission mechanism, a water-cooling cable and the like are involved, and a large amount of working time is required for recovering and adjusting each mechanism after the whole body is installed.
According to the structure of the existing vacuum consumable electric arc furnace, if the dynamic seal assembly is directly separated from the electrode rod and the dynamic seal assembly is taken out from the interior of the furnace body, the requirement on the hoisting height can be reduced; meanwhile, the integrity of other mechanisms is kept, and a large amount of manpower and material resources are saved for recovering other mechanisms. However, this disassembly method has three problems: firstly, the corrugated pipe of the dynamic seal assembly cannot bear pressure, and if the corrugated pipe is stressed, air leakage and loss are easily caused; secondly, in the using process, the friction force between the interior of the dynamic seal assembly and the electrode rod is extremely large due to smelting splashing and lubricating grease agglomeration, and the dynamic seal assembly cannot be separated and fall off directly or manually; and thirdly, the space of the upper parts of the electrode rod and the dynamic seal assembly is limited, and the structure of the disassembling tool is not too complex.
